Struct PerformanceTake 

pub struct PerformanceTake {
    pub source_id: Symbol,
    pub take_id: Symbol,
    pub events: Vec<PerformanceEvent>,
    /* private fields */
}

A captured recording of performance events with a content-addressed cassette.

Stores the raw PerformanceEvents plus a derived stream cassette and a stable content hash, and can replay, convert to notes, or render to Music.

Fields

source_id: Symbol

Symbol of the source that captured the take.

take_id: Symbol

Symbol identifying the take.

events: Vec<PerformanceEvent>

Captured performance events in order.

Implementations

impl PerformanceTake

pub fn new( source_id: Symbol, take_id: Symbol, events: Vec<PerformanceEvent>, ) -> Result<Self>

Builds a take from events, deriving its cassette and content hash.

pub fn cassette(&self) -> &StreamCassette

Returns the stream cassette derived from the take’s events.

pub fn content_hash(&self) -> &str

Returns the stable content hash of the take’s cassette.

pub fn replay_events(&self) -> Result<Vec<PerformanceEvent>>

Decodes the take’s events back from its cassette.

pub fn replay_content_hash(&self) -> Result<String>

Recomputes the content hash from the cassette-replayed events.

pub fn note_events(&self) -> Result<Vec<NoteEvent>>

Pairs note-on/note-off events into timed NoteEvents.

pub fn play_events(&self) -> Result<Vec<PlayEvent>>

Returns the take’s notes wrapped as PlayEvents.

pub fn as_clip(&self) -> Result<Music>

Renders the take into a piano-roll Music clip.

pub fn player_chain_context(&self, cx: &PlayContext) -> Result<PlayContext>

Returns cx with the take’s play events merged into its upstream, ordered.
